Just got the check light off my after repairs. On the drive home the light came on again why? Do I have to drive then it will go out or what.

Have the codes read, usually free at a chain auto parts store.  
My guess, either you have a new problem, or the shop did not fix the old problems correctly.  
You can tell us what was repaired and post the new codes and someone on the forum may suggest solutions.  
Codes will be in the format P0123.

as @Purebred said- we’re going to need more info to offer any kind of input on this.

along with what they asked for, please provide:  
Vehicle mileage  
engine size  
are you having any drivability issues
